8 creepiest places in U.S. national parks

Star Dune, Great Sand Dunes National Park

The park that’s home to North America’s tallest sand dunes is also a flying saucer hotspot. More than 60 UFO sightings have been reported in and around Great Sand Dunes National Park, and the region made national headlines in the 1970s with a rash of cattle mutilations that continue today. If you can’t make it to the nearby UFO Watchtower, the top of the 750-foot Star Dune provides the best view for UFO spotting. Learn more about the park's flying saucer history in the video below.
